You have a pulley 10.2 cm in diameter and with a mass of 2.1 kg. You get to wondering whether the pulley is uniform. That is, is the mass evenly distributed, or is it concentrated toward the center or the rim? To find out, you hang the pulley on a hook, wrap a strin around it several times, and suspend your 1.2 kg physics book 1.1 m above the floor. With your stopwatch, you can find that it takes 0.65 s for your book to hit the floor. Use g=9.8 m/s2. What is the moment of inertia if the pulley is uniform? kg m2 What is the actual moment of inertia of the pulley based on your measurement? kg m? What do you conclude about the pulley? O The pulley is uniform (within 1% of uniform) O The mass of the pulley is concentrated toward the center O The mass of the pulley is concentrated toward the rim

Consider a beam of length L vwith a fulcrum x meters from one end (see figure). There are objects with weights W, and W, placed on opposite ends of the beam, where W, < W,. Find x such that the system is in equilibrium. (Round your answer to three decimal places.) In order to move a 2400-newton rock, a person weighing 800 newtons wants to balance it on a beam that is 5 meters long. W, W

a bucket of water with a mass of 25 kilograms is lifted from a well by a rope which is wound around a cylinder with a radius of 0.10 meters. A 0.50 meter crank is attached to the cylinder so that it wraps the rope around the cylinder. what is the minimum force that must be applied to the crank to lift the water bucket ?
Jackson finds an old well with a rope, bucket, a shaft that spools the rope, and a large crank wheel that turns the shaft to bring up the bucket of water. The bucket and the water have a total mass of 10.33kg, the shaft has a diameter of 15cm, and the crank wheel has a radius of 0.625m. Ignoring the mass of the rope, use torque to find the tangential force on the crank wheel required to lift the bucket and the water at a constanst speed.

A uniform rod is set up so that it can rotate about an axis at perpendicular to one of its ends. The length and mass of the rod are 0.893 m and 1.19 kg, respectively. A force of constant magnitude F acts on the rod at the end opposite the rotation axis. The direction of the force is perpendicular to both the rod's length and the rotation axis. Calculate the value of F that will accelerate the rod from rest to an angular speed of 6.31 rad/s in 8.87 s. F = N

A hanging weight, with a mass of m, = 0.375 kg, is attached by a string to a block with mass m, = 0.865 kg as shown in the figure below. The string goes over a pulley with a mass of M = 0.350 kg. The pulley can be modeled as a hollow cylinder with an inner radius of R, = 0.0200 m, and an outer radius of R, = 0.0300 m; the mass of the spokes is negligible. As the weight falls, the block slides on the table, and the coefficient of kinetic friction between the block and the table is u, = 0.250. At the instant shown, the block is moving with a velocity of v, = 0.820 m/s toward the pulley. Assume that the pulley is free spin without friction, that the string does not stretch and does not slip on the pulley, and that the mass of the string is negligible. (a) Using energy methods, find the speed of the block (in m/s) after it has moved a distance of 0.700 m away from the initial position shown. 1.517 You may have modeled the pulley as a very thin hollow cylinder with a radius of Ra, or as a…

To support the wheelbarrow in equilibrium, the man’s hands apply a force to the handles that is directed vertically upward.consider a rotational axis at the point where the tire contacts the ground, directed perpendicular to the plane of the paper.find the magnitude of the man’s force for both designs.
Suppose you have a machine with a metal disk in it mounted to spin about its center. If the disk has a radius of 0.7 meters, and a mass of 5 kilograms, how much force would you have to apply to its edge to get it spinning at 1200 revolutions per minute. Assume the force is applied for 8.3 seconds. Give your answer in newtons (N).
